Enjoy the new firmware. I have been trying to remain quite and hope for a new update to fix the old. After the latest update I lost C!/C2 also. only option I am given is Toggle screen Map and toggle screen battery. Have I missed something or is this now the norm. Yes, I deleted and reloaded the App. both on my Ipad mini 2 and IPhone 6s.
This has been reported in many other threads regarding the manual gimbal adjustment after switching to DJI Go App 3.0 If this adjustment is important to you, then downgrade back to version 2.92 until they have corrected it.
You might be able to downgrade, sort of speak, via iTunes if the older version of the Go app is what was backed up. Have you tried looking into that? We should have an app update coming out shortly. Android devices have not been affected, if you happen to have one in the meantime as well.
I have the thread link below, but you would need the iPad backed up on iTunes first and then you can roll back to the previous version of the DJI Go App. This is worthwhile to check it out.
